Functionality
The trip circuit supervision function TCSSCBR is designed to supervise the control
circuit of the circuit breaker. The invalidity of a control circuit is detected by using a
dedicated output contact that contains the supervision functionality. The failure of a
circuit is reported to the corresponding function block in the relay configuration.
The function starts and operates when TCSSCBR detects a trip circuit failure. The
operating time characteristic for the function is DT. The function operates after a
predefined operating time and resets when the fault disappears.
The function contains a blocking functionality. Blocking deactivates the ALARM
output and resets the timer.
Operation principle
The function can be enabled and disabled with the Operation setting. The
corresponding parameter values are "On" and "Off".
The operation of TCSSCBR can be described by using a module diagram. All the
modules in the diagram are explained in the next sections.
